| 摘 要： | 给出了一种适合于吸收性介质内粒子散射的Mie级数新的表示形式。利用Mie理论研究了吸收性海水中气泡的单散射特性和气泡群的相位函数。与非吸收性海水中气泡的光散射特性相比，分析了海水折射率虚部对气泡光散射的影响。结果表明：180°后向散射的增强是气泡固有的光学性质，与所处介质无关，可以利用后向散射的增强来探测气泡。

| Abstract: | New form of Mie series which is suitable for particle scattering in an absorbing medium is demonstrated. Both single-bubble-scattering properties and phase function of bubbles in the absorbing sea water are researched based on Mie theory. At the same time, the influences of the imaginary part of the refractive index of sea water on light scattering properties of the bubble are analyzed. The results show that enhancement of bubble backscattering at 180° is an inherent optical property of the bubble and has nothing to do with the surrounding medium, and thus can be used to detect the bubble in the absorbing and non-absorbing sea water. |
